Reference 220.10.34.20.63.001 represents the Aqua Terra 150m collection at its most understated, housing a Master Co-Axial automatic movement that holds COSC chronometer certification. The round 34mm stainless steel case is fitted with scratch-resistant sapphire crystal and a transparent case back, allowing a view of the movement within.
The warm brown dial sits behind a fixed bezel, while the stainless steel bracelet — finished in brushed and polished surfaces — fastens with a push-button folding clasp. Water resistance is rated to 150 metres / 500 feet, lending the watch genuine versatility beyond the wrist.
Offered in new and unworn condition, this Aqua Terra carries no screw-in crown yet delivers the precision and refinement that define Omega's Seamaster lineage in a pleasingly compact case size.
